Обсуждение: Oops: ecpg changes <> to = (not good)

In the process of cleaning up some memory leaks in the cvs tree, I
discovered that
the checked in version of ecpg interperates <> as =:

For example, if you run ecpg on the following:

test()
{ exec sql   select xxx from yyy where zzz <> ppp;
}

You get this output:

/* Processed by ecpg (2.6.11) */
/* These two include files are added by the preprocessor */
#include <ecpgtype.h>
#include <ecpglib.h>

test()
{ { ECPGdo(__LINE__, NULL, "select  xxx   from yyy where zzz  = ppp
",
ECPGt_EOIT, ECPGt_EORT);}
#line 5 "t.pgc"

}



Note that zzz <> ppp has been changed to zzz = ppp.  This is not broken
in 6.5.3.

Not good.

I would debug this myself, but do not understand lex and yacc well
enough yet.

Oops. This typo got in there when I took over the simplified a_expr and
b_expr rules from gram.y.

I already changed it in my source. As soon as I commit the correct version
will go in.

If you need a patch earlier I attach the patch.
